The ilmenite resources stretches of the country and also in inland estimation for the areas explored up to 2012 has placers. Heavy mineral sands comprise a group of been completed and the resources are up from seven minerals, viz, ilmenite, leucoxene (brown 520.38 million tonnes to 593.50 million tonnes ilmenite), rutile, zircon, sillimanite, garnet and (including leucoxene), inclusive of indicated, monazite. Ilmenite (FeO.TiO2) and rutile (TiO2) are inferred and speculative categories. Resource the two chief minerals of titanium. Titanium dioxide estimation for the areas explored during 2012-14 occurs in polymorphic forms as rutile, anatase is under progress. The most significant deposits (octahedrite) and brookite. Though, brookite is which are readily available and attract attention not found on a large-scale in nature, it is an of industry for large-scale operations are as alteration product of other titanium minerals. follows: Leucoxene is an alteration product of ilmenite and found associated with ilmenite.

The overall statewise reserves of ilmenite ilmenite (335.6 million tonnes), rutile (13.4 million and rutile which occur together in beach sand tonnes), leucoxene (1.0 million tonnes), anatase deposits are given in Table-1.
